PFBA1-SP-RFP-cMyc-Snooptag-TPGK1
Characterization-Introduction of Tag-Catcher system to co-display PETase and MHETase
In this assembly, RFP is a RED fluorescent protein, showing red fluorescence, cMyc tag is used for protein purification, and Snooptag will form a tight connection with snoopcatcher, which in turn anchors the attached RFP to the cell surface. Promoter-PFBA1,Terminator-TPGK1.
To attain co-display, we combined our display system with two selective protein binding systems, SpyTag-SpyCatcher and SnoopTag-SnoopCatcher. In our experiment, GFP and RFP were used to indicate the successful construction of Spycatcher/Spytag and Snoopcatcher/Snooptag systems. We initially tried two catcher types with a ratio of 1:3.
